Titan 0509590 Piston Guide Bushing - Aftermarket Replacement | Bedford 44-3235
The Bedford 44-3235 is a precision-machined aftermarket replacement for the Titan 0509590 piston guide bushing, a critical wear component that ensures the stability, alignment, and smooth linear motion of the pump piston rod within the hydraulic assembly. Engineered from high-strength, low-friction materials, this bushing minimizes rod deflection and wear, extending the service life of the entire pump and preventing costly damage to seals and packings, all while providing OEM-level performance and durability at a significant cost saving.
Premium Quality
Precision-Machined
Low-Friction
Why Choose This Piston Guide Bushing
- Precision-machined to exact OEM tolerances for a perfect, no-play fit around the piston rod
- High-strength, low-friction composite material reduces wear on both the bushing and the piston rod
- Prevents rod wobble and deflection, which protects seals and ensures efficient pump operation
- Direct replacement for Titan 0509590, restoring factory alignment and reducing vibration
Common Applications
- Replacement of the guide bushing in Titan 640, 840, 940 series pumps during lower assembly overhauls for serial numbers TIN-15XXXX and later
- Repair for pumps exhibiting excessive piston rod play, irregular hydraulic noise, or accelerated lower seal failure (part# 0509590 specific)
- Preventive maintenance in high-cycle industrial or contracting pumps experiencing over 2,000 hours of annual runtime
- Critical component in pump rebuild kits for models where the OEM service manual specifies bushing replacement at overhaul
Compatible with Titan pump models where the OEM piston guide bushing part number is 0509590.
What It Fits
- Titan Pump Models: Specifically designed for the 640, 840, and 940 series airless pumps that utilize the 0509590 guide bushing in the lower hydraulic assembly. Confirm with your model's parts diagram.
- Replaces Titan Part: 0509590 (Piston Guide Bushing, Lower). Check the part number on your old bushing or in your pump's hydraulic block assembly diagram.
- Specific Use: Installed in the lower hydraulic block to guide and stabilize the piston rod, preventing lateral movement that causes seal wear and hydraulic fluid leaks.
- System Location: Located in the lower hydraulic housing, directly above or within the packing chamber, surrounding the piston rod.
If your Titan pump's service manual or hydraulic assembly specifies guide bushing part number 0509590, Bedford 44-3235 is the correct aftermarket replacement. Not all pump models use this specific bushing.

Installation Notes
- Disconnect power, relieve all hydraulic and fluid pressure, and drain the hydraulic reservoir before disassembly.
- Remove the lower hydraulic assembly/packing chamber to access the old guide bushing. A press or bushing driver may be required.
- Thoroughly clean the bushing bore in the housing and inspect the piston rod for scoring or wear that could damage the new bushing.
- Lubricate the new Bedford 44-3235 bushing with clean hydraulic oil and press it evenly into place, ensuring it is flush and square.
- Reassemble the lower assembly with new seals and packings, refill with hydraulic fluid, and test for leaks and smooth operation.
Pro Tip: Always replace the piston guide bushing, lower seals, and packings as a set during a rebuild. A worn bushing is often the root cause of rapid seal failure.
When to Replace the Guide Bushing
- Visible lateral play or wobble in the piston rod when the pump is off and pressure is relieved
- Repeated failure of lower hydraulic seals or packings shortly after replacement
- Unusual knocking or grinding noises from the lower pump section during operation
- As a mandatory step during any complete pump overhaul or lower hydraulic block rebuild

Frequently Asked Questions
The guide bushing is installed in the hydraulic block and acts as a bearing for the piston rod. It ensures the rod moves in a perfectly straight line during its reciprocating stroke, preventing lateral movement that can cause rapid seal wear, hydraulic leaks, and inefficiency.
Signs include noticeable side-to-side play in the piston rod (with the pump off and depressurized), a history of recurring lower seal failures, or unusual metallic scraping or knocking sounds from the pump's lower section during operation.
Yes. A worn bushing allows the piston rod to deflect, which creates an uneven wear pattern on rod seals and packings, leading to premature failure. It can also score the piston rod itself, necessitating a much more expensive replacement.
Typically, a bushing driver or an appropriately sized socket and arbor press are needed to remove the old bushing and install the new one without damaging it or the housing. Proper alignment during installation is critical.
